us and down和ups and downs有什麽區別？

Ups and downs作為俗語就是指壹個人的運氣時好時壞，或是在某件事上成功和失敗不斷循環。換句話說，ups and downs就是起伏、波折。這是每個人都難免會遇到的。下面就是壹個例子。　例句-1: Mister White sure has had his ups and downs. He's made a fortune three times and then lost it all. But he doesn't have to worry - his wife is rich. When her father died last year, she inherited two million dollars.　這句話的意思是：白先生壹生經歷了不少起伏。他三次發了財，可是後來又全虧損了。但是，他不用擔心，他太太很有錢。去年她爸爸去世的時候，她繼承了兩百萬美元。 而up and down 指“上上下下；前前後後；到處；來來往往”通常指實際的動作。
